Abstract

In general, Vasubandhu was known as belonging to Sautrāntika because he wrote Abhidharmakoṣabhāṣya based on the thinking of the this sect, but Saṃghabhadra provided a totally new fact. Namely,Sautrāntika at that time was a sect of Sthavira Śrīlāta that was Dārṣṭāntika, and Vasubandhu was ‘foreign Sautrāntika’. This thesis argued the following facts about the relation between both parties through Saṃmghabhadra’ suggestive evidence. Vasubandhu was belong to school of Foreign(Bahirdeśaka) also called as Gandhāra or Western(Pāścāttya) at first. This school was a heretic in the inside of Sarvāstivāda opposed to Kāśmīra Vaibhāṣika. But a Sautrāntika of Sthavira Śrīlāta, based in the Eastern(perhaps Ayodhyā), as those who succeeded to Dārṣṭāntika, which was a different school from Sarvāstivāda. Namely, according to Mahāvibhāṣaśāstra,Masters of Gandhāra differed from Dārṣṭāntika in school and phase,therefore Vasubandhu(or his purvācārya) and the Sautrāntika of Śrīlāta who succeeded to them perhaps did so. However, Vasubandhu who associated with one sect of Sthavira wrote Abhidharmakoṣabhāṣya based on their thinking. Thus, the Sautrāntika in the Koṣabhāṣya almost referred to the sect. But he also reported that the theory of Masters of Gandhāra which he actively sympathized with was Sautrāntika(i.e., foreign Sautrāntika)’s. Therefor he was recognized not as ‘master of Sarvāstivāda (Abhidharmika) in the Gandhāra’ but as ‘the one who associated with Sautrāntika(or Dārṣṭāntika)’. Later, some commentators also understood him as Sautrāntika. But Saṃghabhadra who lived in the same age as him understood him as ‘the one with the same views(同見者)’ who turned against Vibhāṣa of Sarvāstivāda and who sympathized with one sect of Sthavira Śrīlāta, and often asked him not to associate with them. It was probably because he originally belonged to the Gandhāra school.
